Somebody already warned in a thread here to always check your visa stamp dates before leaving the immigration desk.
Well Let me tell u - they were right!
I didnt have my glasses on and didnt check until in the car driving to Pattaya. I have a 74 day visa and not 90 as i asked for and was told yes yes 90 day. DO CHECK IT every time. Now i have a trip to make to get it fixed!
